I have the row and column counts from the evidence. Now I need to check for temporal coverage by examining date/timestamp columns across the tables. ```json { "action": "tool_call", "reasoning": "I have row/column counts from step-0. Now I need to identify temporal columns to determine the time period covered. I'll query the column metadata to find date/timestamp columns across all tables.", "tool": "query_sql", "args": { "sql": "SELECT table_name, column_name, phys_type FROM meta.columns WHERE phys_type IN ('TIMESTAMP', 'DATE', 'TIMESTAMP WITH TIME ZONE') ORDER BY table_name, column_name", "purpose": "Find all date/timestamp columns to determine temporal coverage of the dataset" } } ```
